Cationic cyclization involving a remote allene function in the trifluoroethanoluysis of hepta-5,6-dienyl toluene-p-sulphonate
Abstract
The remote allene function participates efficiently in the trifluoroethanolysis of hepta-5,6-dienyl toluene-p-sulphonate, leading to the cyclized 2-methylenecyclohexyl cation.
